A mouthpiece having a vestibular shield overlapping a user's teeth and gums, a gases passageway extending through the vestibular shield allowing for the passage of the gases through the mouthpiece and an extra oral sealing member is associated with the gases passageway. The passageway in use causes gases to be diffused when exiting from the gases passageway. The mouthpiece may have a noseflap to seal the user's nose or provide a passageway for the user's nasal passages. The mouthpiece may have an adjustment arrangement to alter a distance between the vestibular shield and the extra-oral sealing member.

An oscillating positive expiratory pressure system including an oscillating positive expiratory pressure device, an adapter coupled to the device, and a control module coupled to the adapter. The control module provides real time information about the use of the device, and provides feedback and storage of the information to improve the use thereof.

A light-guiding mouthguard assembly has a light-transmittable mouthguard and two light-guiding strips. The light-transmittable mouthguard has a teeth-containing channel formed along a curve as a teeth arch. The two light-guiding strips are located on opposite sides of the teeth-containing channel respectively. Each one of the two light-guiding strips is mounted through two opposite terminals of the light-transmittable mouthguard along the teeth-containing channel. An exterior surface of each one of the two light-guiding strips is light-transmittable.

Maxillary devices and Mandibular devices each have a first housing connectable to a tooth of a user or connectable or integral with a teeth covering, wherein the housing encloses an on-board circuit board and a power source. The first housing of the maxillary devices has a tooth connecting portion, a palate housing portion and/or a buccal housing portion. The first housing of the mandibular devices has a tooth connecting portion and a sublingual portion. Each of the palate housing portion and the buccal housing portion enclose a stimulator having an electrode electrically connected to the on-board circuit board and the power source, and can enclose a sensor and/or a medicament dispenser. The sublingual portion encloses a sensor and a medicament dispenser each of which are in electrical communication with the microprocessor of the on-board circuit board.

A rescue device for a choking victim and a method of rescuing a choking victim is provided. The device includes a first tube that is configured to be inserted into the victim's mouth so as to assist in dislodging a foreign object in the victim's windpipe by creating a low-pressure environment within the victim's mouth. The device further includes a second tube that is configured to allow a rescuer to create the low-pressure environment in the victim's mouth by sucking on a second tube of the device. A filter is positioned between the first and second tubes to reduce sanitary concerns and to prevent the foreign object from becoming lodged in the rescuer's windpipe.

A device includes a body defining a respiration passage in fluidic communication with a filter fitting disposed on a first end of the body and a mask fitting disposed on a second end of the body, and a treatment passage in fluidic communication with the mask fitting. A treatment fitting is disposed on the body and is coupleable to a treatment source such that a seal in the treatment fitting transitions from a closed state to an open state to allow fluidic communication between the treatment source and the treatment passage. The device configured to permit (i) inhalation air and/or exhaled breath to be drawn and/or expelled through the filter fitting, the respiration passage, and the mask fitting and (ii) a respiratory therapeutic to be drawn from the treatment source coupled to the treatment fitting, through the treatment passage, and through the mask fitting.

An embodiment of the disclosure provides a universal sealing apparatus for one or more cannulas. The apparatus includes a first portion, a second portion, and a third portion. The first and second portions are configured to removably adhere directly or indirectly to a nose. The third portion is coupled to the first and second portions. The third portion removably couples to one or more cannulas and places a force upon a base of flared portions of the one or more cannulas when the first and second portions are adhered to the nose. The force maintains a fluid seal of the one or more cannulas within one or more respective nostrils of the nose.

An oropharyngeal airway device includes an elongated hollow body having proximal and distal ends, and a collar secured to the proximal end of the elongated hollow body. The device also includes an aspiration tube and an adapter where the adapter has a first open end and an opposing second open end. The first and second open ends are each coupled to the aspiration tube. In addition, the device includes a delivery conduit coupled to the adapter and positioned within the elongated hollow body in order to deliver gas from a gas supply to the distal end of the elongated hollow body and into an airway of a patient. The device includes at least one fastener within the collar for removably securing the adapter to the collar.

A pressure indicator for a respiratory treatment device, the pressure indicator including an instrument for measuring pressures, a conduit configured to transmit a pressure within the respiratory treatment device to the instrument, and a pressure stabilizer orifice positioned within the conduit.

A mouth cooler is provided. The mouth cooler comprises a first peripheral cooling winding shaped and dimensioned to cool the lower and upper jaw, and at least one second cooling winding in arrangement with the peripheral cooling winding shaped and dimensioned to cool at least the blood entry to the tongue.
